Since Paul was undoubtedly familiar with both languages and Peter may well have gone by both names, as well as considering that Paul often used a secretary to whom he dictated his letters it is not really surprising or significant that we find two different names for Peter within a very short few verses.
As for the manuscript evidence, it appears that only manuscript p46 has a variant reading which uses Peter instead of Cephas in Galatians 2 v 9 (all other references being Peter, Petros).The Chester Beatty Papyri 11 as it is sometimes known is indeed ancient, some regarding it as being from towards the end of the first century, within only 30 years or so of Paul having written Galatians.
The only problem is that oldest is not always the best. This manuscript is well known to be full of scribal errors, which is determined mostly by comparing it with the many other manuscripts available. Thus, the majority of manuscripts greatly favor the existing reading which has Peter mentioned five times (Galatians 1:18, 2:7, 2:8, 2:11, and 2:14) and Cephas once (2:9).
It is a Latinized name taken from an Aramaic word for "rock".
Peter is called Cephas because it is the Aramaic version of his name, which means "rock" in English.
Peter is called Cephas in the Bible because "Cephas" is the Aramaic version of the name "Peter." Both names mean "rock," symbolizing Peter's role as a foundational figure in the Christian faith.
Peter is a Greek name, the Aramaic equivalent would be "Kefa" (more commonly transliterated "Cephas"), meaning "rock" or "stone." You can find the "Kefa" written in Aramaic scripts from a reputable Aramaic translator.--Aramaic Designs (http://aramaicdesigns.rogueleaf.com/)

Peter's name in Aramaic was "Cephas," which means "rock" or "stone." It was translated to the Greek name "Petros," which has the same meaning and is typically known as "Peter" in English.
In the Bible, the name Cephas holds significance as it was the Aramaic name given to the apostle Peter by Jesus, meaning "rock." Peter is considered a foundational figure in the Christian faith, symbolizing strength and leadership.
Peter derives from the Greek petrus which means rock. When Our Lord spoke to Peter he called him Cephas which was Aramaic for rock. This was then translated into Greek when the New Testament was written.
Cephas was another name for Simon Peter, one of the twelve apostles of Jesus. The name Cephas is derived from Aramaic and means "rock," which is similar to the Greek name Peter, also meaning "rock." Peter played a significant role in the early Christian church and is considered one of the key figures in spreading the teachings of Jesus.
"Peter" is named five different ways:"Peter," in Matthew 14:28"Simon" in Luke 22:31"Simon Peter" in Matthew 16:16"Symeon" at Acts 15:14"Cephas" at John 1:42But it was the Apostle Paul who was from Tarsus.Roman Catholic AnswerTo shed some light on the confusion, his name was Simon, that was his Jewish name in Aramaic. Jesus gave him the name "rock" in Matthew 16:18. The word for "rock" is Kephas or Cephas in Hebrew, and Petros (feminine) or Petras (masculine) (most other languages have gender in their words) in Greek (from which we get the name Peter).
Cephas Washburn died in 1860.
